Class DataTypeRegistry.Registerer

A Registerer is responsible for providing allowed DataTypes for a given
provider class. Upon load of a provider class, it should register a
Registerer with the DataTypeRegistry to signify
that it has DataTypes. Then when a query is first made for the DataTypes
of that provider class the Registerer will be called to
register those types before the query is performed.
